Vlasov modelling of parallel transport in a tokamak scrape-off layer
A one-dimensional Vlasov-Poisson model is used to describe the parallel transport in a tokamak scrape-off layer. Thanks to a recently-developed ‘asymptoticpreserving’ numerical scheme, it is possible to lift numerical constraints on the time step and grid spacing, which are no longer limited by, respectively, the electron plasma period and Debye length. The Vlasov approach provides a good veloc...

متن کاملSimulation of the scrape-off layer region of tokamak devices
Understanding the key processes occurring in the tokamak scrape-off layer (SOL) is becoming of the outmost importance while we enter the ITER era and we move towards the conception of future fusion reactors. By controlling the heat exhaust, by playing an important role in determining the overall plasma confinement, and by regulating the impurity level in tokamak core, the dynamics of the fusion...
متن کاملTurbulent regimes in the tokamak Scrape-Off layer
◮ We study Scrape-Off Layer (SOL) turbulence through simulations that evolve the plasma dynamics as the interplay of plasma source from the core, perpendicular transport, and losses at the limiter plates ◮ We identify the SOL turbulence regimes, defining the regions of existence of the Ballooning Modes [resistive (RBM) and inertial (IBM)] and the Drift Waves [resistive (RDW) and inertial (IDW)]...
